hutool poi 分頁導出，格式設置

    @RequestMapping(value = "/exportXls")
    public void exportXls(HttpServletRequest request, DnbUser dnbUser, HttpServletResponse response) throws IOException {

        ExcelWriter writer = ExcelUtil.getWriter();

        List<DnbUser> dnbUsers = dnbUserService.list();

            generateStyle(writer, i, styleEndIndex,dnbUsers,startIndex);
        }
        response.setContentType("application/vnd.ms-excel;charset=utf-8");
        response.setHeader("Content-Disposition", "attachment;filename=test.xls");
        ServletOutputStream out = response.getOutputStream();

        writer.flush(out, true);
        writer.close();
        IoUtil.close(out);
    }

    private void generateStyle(ExcelWriter writer, int sheetNo, int styleEndIndex,List<DnbUser> dnbUsers ,int dataStartIndex) {
//        Workbook wb = writer.getWorkbook();
//        Font font = writer.createFont();
//        font.setBold(true);
//        font.setColor(Font.COLOR_RED);
//        font.setItalic(true);
//

//        CellStyle cellStyle = style.getCellStyle();
//        cellStyle.setLeftBorderColor((short) 999);
//        cellStyle.setFont(font);

        Workbook wb = writer.getWorkbook();
        CellStyle cellStyle = wb.createCellStyle();
        cellStyle.setAlignment(HorizontalAlignment.CENTER);
        cellStyle.setBorderBottom((short)1);
        cellStyle.setBorderLeft((short)1);
        cellStyle.setBorderRight((short)1);
        cellStyle.setBorderTop((short)1);
        cellStyle.setFillPattern((short)1);
        cellStyle.setFillForegroundColor(HSSFColor.HSSFColorPredefined.RED.getIndex());

        Sheet sheet = wb.getSheetAt(sheetNo);
        for(int i = 1; i <= styleEndIndex; ++i,dataStartIndex++) {
            if(dnbUsers.get(dataStartIndex).getNo().equalsIgnoreCase("1")){
               sheet.getRow(i).getCell(13).setCellStyle(cellStyle);
            }
        }
    }

 

導出結果：每sheet頁4行，特定單元格設置格式。

屬於測試數據，數據不嚴謹。hutool的依賴，記得加入pom文件。
